In this study, we classified ortho‐phenylene‐naphthylene oligomers into three types II, III, and IV based on the sequence of phenylene and naphthylene units. Type II has an alternating sequence of phenylene and naphthylene units, type III has a phenylene‐naphthylene‐phenylene repeating structure, and type IV has a naphthylene‐phenylene‐naphthylene repeating structure. While type II has been studied in detail, there have been few reports on types III and IV. We report on the synthesis and photophysical properties of oligomers with type II, III, and IV substructures. Additionally, X‐ray crystallographic analysis confirmed that these oligomers adopt helical conformations.
